It is an object of this invention to provide a yarn carrier paintingapparatus in which'an improved mechanism is employed for moving amarking brush into contact with a carrier, and also in which an improvedmeans is provided for holding the brush in contact with the carrier fora predetermined length oftime.

Specifically, the improved structure, in part, comprises a rotatingspindle for supporting a yarn holder, in combination with a'cam forpositively moving a paint brush toward and away from the holder, and aclutch for connecting and disconnecting the cam with a suitable drivingmeans,

The improved structure insures that each carrier will be engaged by thebrushfor the same length of time and thereby will receive a I marked.

coat of marking material substantially the same as the coat applied toeach of the preceding carriers.

It is another object of thisinvention to provide a marking apparatusofthe class described in which manually operable means are provided forconnecting the brush advancing cam with its driving means, and automaticmeans for disconnecting said cam from its driving means after a coatingof marking material has been applied.

Some of the objects of the invention having been stated, other objectswill appear as the description proceeds, when taken in connection withthe accompanying drawings, in which Figure l is an elevation of myimproved coating apparatus for yarn carriers and the like;

Figure 11 is an isometric view showingthe cam means for pumpingpredetermined quanti-' ties of markingmaterial upon the brush, and alsoshowing means for turning the brusha' partial: revolution each time ayarn carrier is Brush support and advancing structure Referring morespecifically to the drawings, the numeral lfldenotes' a suitable basemember which has extending upwardly from the central portion thereof asuitable shaft ll. Thisshaft hasintegral with its upper portion arestricted shaft portion lla around which a sleeve or pipe I2 isrotatably mounted, said sleeve havingone end of :a lever l4 securedthereto. This lever ex tends downwardly and thenlaterally, and has asuitable slot iii in the outstanding leg thereof, which is penetrated byan upstanding arm IS. The arm I6 extends upwardly from a horizontallydisposed shaft ll, said shaft ll being rotatably mounted in a suitablehearing such as counter casing I8. Shaft ll has another arm l9 extendinglaterally therefrom, and the free end of this arm l9 rests upon theupper end of a vertically disposed plunger 20, which plunger is mountedfor vertical sliding movement in a suitablecollar 2| secured in basemember l0, previously de-' scribed. A suitable cam.22 is provided insuch a position that the lower end of the plunger will rest upon theperiphery thereof. Therefore, as the cam 22 rotates the sleeve I2 willbe oscillated back and forth around portion I la by means-of members [4to 20. Thepurpose of providing the oscillating sleeve I2 is to havemeans whereby a suitable paintbrush or other marking means 28 canbe-moved into and out of contact with This brush and associatedmechanism is mounted upon a suitable bracket 25, said bracket beingsecured to sleeve 12 by any suitable means such as screws 26. Rotatablymounted in the bracket 25 is a brush shaft 21 (Figure 8) said brushshaft having secured on the projecting end thereof brush 28. As thebrush 28 swings laterally through an arc whose center is shaft Ha(Figures 2 and 3) the end of the brush contacts the upper end of yarncarrier 30. The carrier 3B is removably mounted on a suitable spindle 3I.

Yarn carrier support and rotating means The spindle 3| has a whorl 32integral with the intermediate portion thereof, and the lower portion ofspindle 3| is rotatably mounted in a bolster 33 which, in turn, issecured to supporting member l0. As a means for constantly driving thewhorl 32, spindle 3| and the yarn carrier 30, a suitable belt 34 isprovided which belt 34 is also mounted upon a pulley 35 secured on theend of a motor shaft 35. This motor shaft is driven by a conventionalmotor 31 mounted on the support I0.

Since the yarn carrier is constantly rotated by the motor 31, a supplyof coating material which is on the brush will be applied to the yarncarrier each time the brush 28 is advanced to contacting position. Thebrush 28, however, is moved into engagement with the tip of the yarncarrier 30 by means of the cam 22 previously described. As a. means fornormally rotating the brush 28 away from the yarn carrier 30 and forholding plunger 30 in engagement with cam 22 at all times, a suitabletorsion spring ;49 is provided (Figure 2), one end of said torsionspring being secured to shaft l1 and the other end of the torsion springbeing secured to counter housing 18.

. This torsion spring normally rotates the shaft I1 and its associatedarms I6 and I9 in a counterclockwise manner in Figure 1 to thereby causethe brush 28 to be normally forced away from the observer. It is onlywhen the positive force exerted by'the rotation of cam 22 is appliedthatthe force of the spring 28 is overcome and the brush 28 is moved todotted line contacting position as shown in Figure 2.

Brash rotating means It is preferable that the brush 28 beintermittently rotated about its axis so that all portions thereof willcontact an object to be marked in a continuous operation. If only oneside of the brush were to contact the yarn carriers, the bristles wouldbecome set in one position and would.

not apply a uniform coating of paint to the yarn carriers after a shortperiod of use. By providing means for rotating the brush to differentpositions, all sides of the brush are permitted to contact carriers andtherefore a much more satisfactory marking operation is effected. Thisrotation of the brush 23 is produced by a structure that will bepresently described.

1 By referring to Figure .8. it will be seen that the shaft 21 hasfixedly secured therearound, a pinion 48, said pinion meshing with alarger pinion 49, which, in turn, is rotatably mounted upon anothershaft 50. This shaft 50 is secured in bracket 25. Integral with thepinion 49 is a ratchet wheel 5|, the teeth of which are engaged by asuitable pawl 52.

By referring to Figures 3, 4, 8 and 11 the details ofpawl 52andassociated structure can be seen.- This pawl is L-shaped'and is pivotedintermediate its ends as at 53, to the lower end of a bracket 54, saidbracket having a laterally disposed leg 55 in which a verticallydisposed bore 56 is provided (Figure 11). This bore fits overthe upperend of shaft Ha and is rigidly secured thereto-by any suitable meanssuch as a set screw 51. In order to normally urge the pawl 52in acounter-clockwise manner in Figures 3 and 11, at all times, a suitablecompression spring EQ-is provided, one end of which is firmly pressedagainst the vertical leg of the pawl by any suitable means such as aheaded screw 60. This screw penetrates a suitable slot 6| (Figure 9) inthe vertical leg and-has the small and thereof threadably mounted in thelower end of bracket member 54.

Especial attention is calledto the fact that the parts 52 to 69inclusive remain substantially in a stationary position except for thelimitedarnount of rotation permitted pawl 52. On the other hand, thebracket 25-together with-its associated membersZG, 21,28, 48, 4Q, 50,and El are mounted for rotation as a unit around shaft Ha. In otherwords, the brush 28 moves laterally from the position shown in Figure 3to the position shown in Figure 3A, during a marking operation. Thislateral movement of the brush 28 along with the ratchet wheel 5| issufficient to cause the free end of the dog 52 to engage an adjacenttooth in the-ratchet wheel 5 I, and therefore when the ratchet wheelreturns to the normal position as shown in Figure 3, it will be rotateda distance of one tooth to thereby cause pinions48 and 49, shaft 2-?-and brush 28 to rotate a corresponding amount. The teeth of the ratchetwheel 5! are also engaged by a locking dog said dog having its upper androtatably mounted in bracket 25 as at 65, and having its free endnormally engaging one of the notches in the ratchet wheel. Member 65prevents reverse rotation of the ratchet wheel 5| and its associatedparts and thereby insures that the brush 28 will remain in the positionto which it has been rotated while'thedog 52 is moving reversely overthe ratchet teeth It will also be noted that by observing Figures 3 and9 that the bristles of the brush 28- are flattened into a compact mass,the flattened side of which is disposed at anacute angle to a verticalposition. By placing the flattened brush 28 at this angle, it is in abetter position to receive the contents such as paint and the like froma dispensing pipe 10' thereabove.

' Dispensing mechanism for the marking material It is verydesirable'that, a predetermined quantity of marking material may beapplied to the brush 28- each time a ya fnholder is painted or .marked.Unless such a mechanism is provided,

viding this dispensing mechanism a suitable plate a ua e His securedtothe upper portion of bracket by any suitable means such as ascrew 12This plate member H formsa baseupon which a container M is adaptedto'removably fit.. In order to hold the container l4 upon the platform ii asuitable spring lip 15is provided, which spring lip forms an integralportion of plate.

member 1 l. The lip 15 has a hole 76 in the ver; tical leg thereof whichhole fits over a pin or'projection 71 extending from one side ofcontainer MI When the lip 75 is in the position shown in Figure 8, theoppositeside of the cam 74 pressed into hooked portions 19- to therebyhold the' container in clamped position. This con- Another bore 88 isprovided in alinement with bores 83 and 87 This last-named bore 89,communicates with a vertically disposed cylinder 90 in which is slidablymounted a piston iii. Lead,-

ing from the upper side of piston 9i i is a rod 92 which slidablypenetrates a cap member 94 which cap covers cylinder 90. On the'upperendof rod 92 an enlarged head 96 is providedfor confining a spring 98around rodQZ.

It, willbenoted that the spring s3 normally tends to-iorcepiston 9i,shaft 92, and head 96 upwardly at all times. ;Of course, when.membersill, 92 and 96 move upwardly, a charge of painter marking fluid B0 isdrawn. inwardly throughbores 83, 81 and 89 and into cylinder 99.

Leading from the lowerportion of the cylinder 90 is another bore 99 overwhich alballlfiil is adapted to fit, which ball is disposed inside of ane nlarged bore lfll. This enlarged bore IOI has accompression spring Hi2therein fornormally pressing the ball lilii over the openingior bore Asa means for confining spring 102 within the bore lill, one endof a,suitable L-shaped dispensing pipe 78, previously, described, isthreadably secured in the end of bore Iiil. Ball serves as a check valveas piston 91 moves downwardlyv to discharge the contents from cylinderwhereas ball Nil) serves as a check valve While piston 9|; movesupwardly to draw a supply of marking material into the cylinder Bil.

When the brush 28, together with container l4, fitting 82, anddispensing pipe 70, is moved 1 from the position shown in Figure'3 tothe position shown in Figure 3A, the upper end of head portion is notdepressed by any mechanism,

and therefore, is moved upwardly the maximum amount by spring 98, wherea full charge of marking material will be drawn into cylinder 90.

When the parts justnamed return to normal position as shown in Figure 3,the head portion 96 is automatically depressed to lower the piston Siand to discharge a predetermined portion of marking material from thecylinder 99 through I boresiiii and iii! and 28;

Thi s'means for engaging and depressing the head portion 96 comprises asuitable T-shaped bariiiE, the upperportion of said bar being piv-roted'as at W6 to the bracket member 54. One of the laterally disposedlegs of this bar 95 has through pipe 18 onto brush a'cam-surface I01formed on the lower side thereof which serves asa base against whichthehead portion '96 slidably contacts when it moves,

from the position shown in Figure 3A to the position shown in Figure 3.

In order to insure that the lower portion of the lower cam surface l 0 1will properly engage'thej headv portion 96, a suitable spring I I0 isprovided. This spring is disposed between the vertical legs of theT-shaped member 15 and the face of bracket 54. A pin or screw III hasone one thereof-threadably secured in the vertical leg of T\-shaped bar185, said pin penetrating a slot H2 inthe bracket 54, and supporting thecompression spring lllltherearound, This compres sion normally tends; torotatethe T-shaped bar; 35 in a clockwise manner to the position shownin Figure 3A, when the brush 28 is in contacting position iwith;holder30. I As; thebrush returns to normalposition as shown in Figure 3, alongwith the containerlfl and fitting 82,-the, head portion 96 will movebeneath thecamsurface, I 9'! and the farther it moves to the right inFigure 3, the more the head portion 36, together with cylinder 9! willbe depressed. ,In other words, the piston 9| is depressedby cam surfaceIt]? as a result of therotation of member I05- when itsv vertical legis" engaged bythe moving bracket 25 durin the return of the parts tonormal positionas shoWn-in Figure 3.

Clutch mechanism From the foregoing description, it is seen that as cam22 (Figures 4, 5 and 6) rotates, the brush 28 is moved to paintingposition. Also as the brush moves from painting positionback to norme]position, ajpredetermined amount, of markiri'g material is'disc hargedupon the brush for the next'succeeding marking operation.

whereby the movement of the cam 22 can be properly controlled to producethe marking and dispensing operations. heretofore. described. The

cam 22 is freelyrotatablymounted upon a suitand 5),, said shaft; H5, inturn, being rotatably mounted-in a-suit- I able bracket I i6,'secured tothe lower portion of able shaft H5.(Figures 2, 4,

support Ill. Theshaft H5 has a worm gear II! secured on the end remotefrom thecam 22,;and meshing with this worm geanis'a suitable worm v H8which is f xedly secured upon motorshaft die-3.1 and the associated yarncarrier 30 will be constantly rotated. At the same time, the shaft H5will be rotated but since the cam 22 is loose- 1y mounted therearound',the cam will normally remain stationary. Asa meansfor connecting a shaftl I5 to the cam 22, a suitable disk i 25 is fixedly secured around theshaft il5. Said disk has a plurality of radially disposed spokes orprongs I26 which are adapted to engage a suitable plunger I21 extendingfrom plunger [30in the cam 22.- Especial attention is called to the factthat each of the spokes I23 has abeveled 1 facel26a adjacent the plunger52'! tothereby insure that the plunger I27 will move betweenthe spokeswhen it is desired to connect the cam 22 tothe shaft H5. This camsurface i260, is

disposed on the back side of the spokes from the side which engages theplunger I21, and serves 'to permit the plunger to move laterally inwardbetween the spokes instead of being stopped before entering, When theplunger I21 is disposed betweentwo adjacentspokes I25, it forms a tiebetween'memberlZS and cam member 22 and It is desirable to provide asuitable clutch mechanism When the motor 31 is in operation, the spin- 7therefore causes the cam 22 to" rotate along'with shaft H5.

By observing Figure 7, itwillbe seen that th'e" plunger I2? is slidablymounted in a second plunger I30, saidplunger I3llin-turn;-being'slid- 5=ably mounted in the cam 22. -A- suitablecom pression spring lSI normally forces the plunger" I 2 Plateral-ly from theplunger I Swat alltimes; but when the plunger= I ZI'isddextended position" it"will notnormally project into the-path of the spoke s I ZG-unless theplunger-I3fihasbeenmoved laterally from its normalpositionas'sh'ownin-Figure '7. The plungers I21 and lBEl-are held in normal position, thatis in the'position-where-the endof plunger I21 will not contactspokesIZt-bw any suitable means such as compression spring- I35 disposedaround the plunger I30v Theplungers I21 and' I3ilare' pushed to-theleftin Figures 4 and '7 by means-of-a suitable-L-- shaped lever I36. Thislever'I36 'hasits-upper'-' end pivotally mounted as at- I31 ina-brack'et- I38, said bracket I3B-"being;securedto the lower portion ofsupport H]; Fixedly-secured to lever l36 as at I3! is an L-shapedrodI39? said rod I39-having its free endpivotally seemed as at" 25 I40 to alower end of vertically disposed shaft I4I. This shaft I 4| is slidablymounted in=the supporting stand Ill and projects -vertically'up-'-wardly therethrough; On the upper end of shaft- MI is a button or handrest M4 upon which downward pressure is applied when it is desired torotatethe lower end of lever I36 to the left in Figure 4 and therebypush the plunger-"I21 between two adjacent spokes I26, thereby"connecting the cam 22 to the driving shaftllfi: A"

mit the plunger IE! to remain out of the pathof spokes I26.

When the hand rest I44 is depressed, however, the lower end of-leverI36' (Figurei) i will be pushed inwardl to push plungers I21 and.l30'farther into the cam 22. If the spoke I2B'ha'pe 45 pens to be disposedin the path of the plunger I27 when such pressure is-applied tothefh'and rest, the spring 21o will be depressedwhile' the plunger I 39continues to move inwardly. Since. the rotation of the wheel I25'isrelatively fast it is only necessary for pressure to be appliedvto thehand rest I44 for a veryshort period of time until th spoke I26 willpass by the engaging; plunger I27 sufficiently to permit spring IZTd toforce the same to dotted line positionbetween the spokes.

Upon the engagement of' theplunger IZT'by. one of the spokes I25, thecam 22 "together with. the plungers I27 and 'I30will bebodilyjrotated'labout shaft I55. As this plunger I30"rotates a slight amount from theposition shown infig e ures 4, 5 and 7, the head of said plunger-will."engage a suitable camsurface I50 which surface is cut the face ofbracket I38. In other words,

by exerting manual pressure on' the 'hand'rest' for a very shortinterval of time,:the plunger I30 1' will be bodily rotated about shaftH5 until *tlie. head of the plunger moves into engagement with. the camsurface I50; and this cam suriace'will." positively hold the plunger inadvanced position for almost a complete revolution of shaft'll'li.

When a complete revolution of cam 2'2"has been made, "the head ofplunger I36 willagain slide into a notch I5I out inthe vertical face ofbracket lifat The handpressure'willhave been reissue-e4 relieved fromthe handrest during. the rotation ofthe cam and therefore the lower'end' 1 of the" lever I3 6*wil1 be'ret'racted to normal position by theforce of spring "-I 35; consequently plunger I11 will 'be disposed inanon-obstructing" position relative--11; wheel I 25 whenthe plunger" I30*com: ple'tes this revolution and again enters the notch" It isthereforeseen' that this improved clutch:
